[PATCH 1/1] Properly check return values of kmalloc and vmbus_recvpacket
Correct ugly oversight, we need to check the return values of kmalloc
and vmbus_recvpacket and return if they fail. I also tightened up the
call to kmalloc.
Thanks to Evgeniy Polyakov <zbr at ioremap.net> for pointing this out.

The hv_utils module will be composed of more than one file;
rename hv_utils.c to accommodate this without changing the module name.

[PATCH 00/07] Remove and replace all un-needed DPRINT and printk
This patch set removes all un-needed DPRINT and printk calls and replaces
the remaining ones with the correct pr_, dev_ and netdev_ calls
from hv_vmbus, hv_netvsc, hv_timesource and hv_utils.
Several DPRINTS are remaining that will be cleaned up in my next
set of patches. They deal with printing out certain debugging that will be
implemented slightly differently.
